TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed December 15, 1909. Serial No. 533,309.

To all whom it may concern Be it known that I, \VILLIAM J.. N EIDIG, a citizen of the United States, residing at Madison, in the countyofDane, State of Wisconsin, have invented a certain new and useful 'Improvementin Type-Writing Machines, of which the following is a specifi-.

cation, reference being had therein to the accompanying drawings,

Certain principles and features of my invention as described hereinare included within the generic invention which is described and claimed in my co-pending application filed April 20, 1908, Serial No.

The objects of my invention are broadly to indicate to the operator by automatic 111821115 the position of his current line upon the sheet, either relatively to one of the edges thereof, or to certain other-line positions.

Theobjects of that form of my invention more specifically illustrated in the drawings herein described are, first, to indicate to the operator the distance to the bottom edge of his sheet, or the bottom line of,

his page, from his current printing point, and this line by line and autoinat1cally,be-

ginning as far up the sheet as may be found convenient; second, to give him a preliminary eye signal upon the approach of the end of the sheet; third, tosupply him with a signal. preferably an ear signal, upon the completion of his predetermined last or neXt-to-the-last line or both of the said lines; fourth, to then lock the machine and rcnder it inoperative; fifth, to enable him then to unlock the machine for further printing: and sixth, to supply certain means adapted to be applied to other papermovement-indicating usesof the same gentor with a system of adequate signals View, looking from the front, tion on the line 88, Fig, 1, .ing partly broken away; andFig. 9 isa whereby he may know when to stop his page; and in addition I measure for him the unusedspace leftupoii the paper-sheet,

beginning long before the time to remove it, and continuing to the very end, so that without preliminary care on his part hefcan look aheadat any time and tell whether he has room on hissheet for a group of matter like a foot-note, or a table, or a chapteiheading, that cannot conveniently be dividechand thus stop his page in advance of the predetermined page-length. This func- Patented Feb. 18,1913;

tion has never before been performed, but

is novel to my invention.

I attain my several ob ects by the mechanlsin illustrated in the ings, in which Figure 1 is an end view of the preferable application of my principle as specifically shown herein; Fig. 2 is a front view of a portion of the same; Fig. 3 1s a detail end view of a typical modification;.

My invention as more particularly de-' scribed herein consists of a detainable rot-a part connected more or less directly with the parts throughout the several drawplaten by means embracing a clutch; indieating means controlled or operated by the rotary part, comprising a series of indice's,

an eye signal, an rear signal, and means rendering the machine inoperative,.whether oneor all; and means controlling the action of the clutch, whereby the rotary part upon reaching a certain'constant rotative posit-ion" isrelcased from-enga ement with theplaten and detained until the sheet becomes suit-' rendering the printing mechanism of a type writing machine inoperative at a .predetermined line position, and for restoring the printing mechanism to operativeness at will without loss ofline position, and for automatically.restoring the printing mechanism ,to operativeness for later printing; oertain novel features of clutch-construction; and sundry other novel features, as will be explained.

Referring to the drawings, the usual main frame of a typewriting machine is indicated at 41, on which the transversely movable carriage-frame 12 is mounted, bearing'journaled in the ends thereof the platen-arbor 13, on which is fixedly attached the usual platen 10, all in well-known manner. The line-space mechanism for advancing the platen to feed the sheet-is not shown herein, but may be ofany approved type, as in practice. The usual paper table 8 for the sup port of-theentering sheet is shown, as are the.:paper guards or fingers S1 .aroundthe under side of the platen, all being attached in usual manner to carriage frame 12. The wellknown type-keys 59, space-key 39, and key-levers 38 are shown, the latter being connected in practice with the usual typebars, 78', mounted in usual manner. The platen as regarded herein is a means for feeding the sheet.

Fixedly attached to the platen arbor, and therefore moving simultaneously with the platen, is wheel 11, supplied with notches or interdental spacesaround its periphery. Overhanging this wheel is an independently revoluble drum 6, hereinafter referred to also as the index-carrier, or indicator, the said drum having a removable side com prising the shouldered face-disk 16 and the annular plate 67. Face-disk 16 is attached to the main portion of the drum by screws 43- (Fig. 1), bushings 42 holding the two parts separated for wheel 11, which is revoluble between them. Such construction provides conveniently for assembling the parts. Annular plate 67 is adjustable angularly upon the main structure of the drum, and is used for adjusting the time of actuation of my bell-striking and locking mechanisms. The said annular plate carries attached thereoi'i the outwardly projecting pin 68, the pivoted lock-bar 18, and the expandin'g spring 35, one nd of which presses It includes also a paper-feeler against the lock-bar; and it is shown as havmg a bearing upon the shoulder of disk 16, a part of whose periphery is supplied with the locking recesses 61, into which the said tionship between the. drum and the said wheel, so as not to cause false motion of the drum. In this case Iavoid such false motion by journalingarbor 53 at a point radially exterior of said wheel, and by placing tooth 52 in such position on said clutch-lever that it seats and unseats radially. The form given to the said clutch-tooth and to the cooperating teeth or interdental spaces on said wheel contributes to the result. The form of the teeth and the arrangement of parts is also designed to control the momentum of the drum and prevent the slipping of teeth following the usual sudden arrest of the platen after the completion of a spacing stroke of the line-space lever. Lever32 is supplied with an arm 54, against which presses spring 55, attached 'on the rear wall of the drum, the pressure thereof tending to press tooth 52 intoclutch'with wheel 11. The said end of lever 32 bears a laterally extending projection 1 1 movable in a shortarc in slot 77 in the rear wall of the drum, shown by dotted lines in Fig. 1. In this embodiment of the'invention as a matter of convenience the projection 14 is extended inwardly toward the platen. mount projection 14: as shown in Figs. 1, 2,

4 and 8, so that the lever bearing it will befor structural reasons, but the parts can be constructed otherwise, as is illustrated in Figs. 3 and 5 and hereinafter explained. 1Vl1enpr0jection 14: is. pressed in the direction opposite that in which it rotates, lever 32, rocking on arbor 53, lifts'to-oth 52 out of I prefer to I clutch with wheel 11, whereupon the drum becomes disconnected from its means, and detamable.

Leaving the group of partsjust described,

driving the carriage frame 12 has attached to it by means of screws Gel-the frame-extension 22, the upper part of which bears the inwardly projecting shouldered axle 20,- Figs. 1, 8 and 9.

Journaled upon this axle is hub or sleeve '21, bearing near one end the ,fixedly attached weight-lever 74, upon which weight 66 is adjustably carried, the weight being fastened by set-screw 7 3 at any required distance from the axis thereof, according to the required leveragel Adjacent to this weight-lever, and maintained in lateral position by it on the one side and by the shoulder of axle on the other, is the loosely mounted stop or controller-lever 15, movable in a plane coinciding with that of projection 14. This stop, journaled to turn on sleeve 21, performs the functions of both stop and lever, and normally projects into the path of the projection 14 previously described, being maintained in suitable angular position by the cooperation of lug 63 on 'the said stop-lever 15 with a one-way stop or pin 62 on the weight-lever, the weight of stop-lever 15 holding the said lug in contact with the said one-way stop. The said oneway stop 62 also cooperates with lug 17 on axle 20 to linnt'the movement in one d1rect1on of weight 66, and consequently of sleeve 21. That is to say, stop-lever 15 if moved in one direction will act to change the position of weight 66, through lug 63 and one-way stop 62. \Vhen force ceases to be exerted upon said stop-lever in said direction,weight will return by gravity until stopped by contact of pin 62 with lug 17, its superior weight acting against the weight ofstop-lever 15 to carry said stop-lever back with it, thereby positioning said stop-lever. If

moved in the other direction, however, as by the backing-up of projection 14 against it, stop-lever 15 will not be operative upon the weight, lug63 separating from one-ways'top 62 and permitting idle movement of the stop-lever in that direction. Thus free backing-up of projec-tion14 past stop-lever 15.

is provided for. I regard the provision as desirable, although my invention does'notnecessarily require the use of a stop having any novel or special characteristics. At the other end of hub or sleeve 21 is the fixedly attached feeler-butt 28. Upon this feeler butt, and eccentric to the axis thereof, is pin 23 (Fig. 1) ,.upon which is journaled feeler tip 28, the parts being so mounted that when sleeve 21 is rocked,1 feelertip 28. will be. .moved into the papef-path, provisionbeing made for such movement in this instanceby providing the usual paper-table 8 of the typewriter with a slot or opening 4 in the path of the said feeler-tip, the paper-path being adjacent: the surface of the paper? table. A lug 65 on the tip portion of the paper -feeler cooperates with a one-way stop.

24' on the feeler-butt to limit the movement of the feeler-tip' and feeler butt I relatively to each other, the said parts beingmovable one on the other in a direction separatlng said-lug.v from .said

one thereof with respect to the other, but to limit said movement in the other or working direction. The purpose of this give.-

way provision is to permit free-"backing-up of the sheet from any position thereof. The exact position of the provision in the intermediate train of parts is more or less immaterial, as is its exact form, and a paperfeeler may in some cases be employed hav ing none or' fe-w of the specialcharacteristics of the paper-feeler just described, as is illustrated in Figs. 3 and 5 and explained hereinafter. The paper-fe'eler described has a normal position retracted from the paper- I path, to permit of free sheet-insertion. Upon the passing of pro'ection 14 from con trol of stop-lever 15, weight 66 rocks sleeve 21, thereby moving the attached paperfeeler out of thepaper-path and away from the same, until stop-pin 62 comes in contact with positioning lug 17. In this position the -parts' will remain until projection 14 again presses upon stop 15, an action that ordinarily will not occur until a new sheet is inserted and advanced. Other novel ac- .tion of the paperfeeler will be explained later.

, The action of the niechani'sm thus far described is as follows The paper-sheet 45 is entered into the machine and advanced as usual-by the platen, the paper-feeler occupyingits retracted position and permitting unobstructed sheet-insertion. Drum 6 (and its attached parts) is rotated with the platen duringthis forward movement of the sheet tion 14 willebe brought around into' contact with stop-lever 15, maintained in'the path thereofby weight 66. Further advance of the platen and drum, will cause projection 14 to act opera-tively upon stop-lever 15,

thereby through lug 63 and one-way stop 62 elevating weight 66, rocking sleeve 21, and moving the paper-feeler toward the paper-path. 'If. the paper-sheet were notvpresent, the sheet-contacting portion of the pathrough the action of clutch-tooth 52 and ;wheel,11, as explained. Eventually projecper-feeler would now move into slot 4, stoplever 15 would continue to move ahead of projection 14 until entirely removed from the'path thereof, and drum 6 would continue to move with the platen. But in the presenceof the sheet over slot 4 the paper-feeler cannot enter said slot, and stop-lever 15 consequently can no longer move ahead of projection 14c, but becomes acontrolling stop in the path thereof, as illustrated in F ig. 1.

Further rotation of drum 6 under the actua tion of the platen will now cause lever 32 to be rocked upon axis 53 and tooth 52 to be lifted radially out of the interdental space.

on toothed wheel 11 in which it has been seated, therebv unclutching drum 6 from connection witlfthe platen and permitting detention of the drum by projection 14:. In this position of parts the mechanism will re main during the control of the paper-feeler by the sheet. Meanwhile the sheet will be advanced by the platen until the bottom edge of the sheet arrives at the paper-feeler. The moment the end of the sheet clears the apert'eeler, the said paper-feeler will be leftree to move into slot 4, stop 15 connected therewith will instantly cease to have a stopping action upon projection 14 but will move ahead thereof out of the way, and spring 55 will instantly through lever 32 move tooth 52 into clutch with wheel 11. Drumfi by reason of such action must instantly begin moving with the platen, and it must now continue to revolve securely with the platen until the clutch-mechanism is again released. Other forms of clutch may be used, and other methods of controlling the-same, as is illustrated in Fig. 5 and explained'hereinafter, without departing from the general mode of operation disclosed herein.

I have described a means whereby the rotarydrum 6 is brought to a stop always at the same rotative point, given the presence of the work-sheet. Since the drum comes to a stop always at the same rotat-ive point, it follows that it resumes its movement always from the same initial or starting point. Also, it instantly begins its working movements when the sheets bottom edge has arrived at a fixed distance from the printing point, and thereafter moves in unison with the platen, and therefore coordinately with the sheet. That point upon the drum or carrier which lies opposite the pointer or stationary index 34, conveniently attached to the paper-guard 31, during detention of the drum by step 15 may be marked with a small circle or index 89, to indicate that position of the drum. lVhen the drum given movement with the platen after release the sheet a new point thereon will be brought opposite the stationary index. This point can be marked to indicate the distance then remaining between the current printing point and the sheet-end, for .the same point on the drum will always come into indicating position when the sheet-end arrives at the given distance from the printing point. Let us say that this. distance is seventeen single linespaces. I mark my drum or index-carrier distance. And so on, down to 1. Such are the numerals shown in the drawings. Any

distances desired within the range of the mechanism can be indicated in the same way, beginning with any sheet-position and end ing with any and omitting any. Instead of using single-line indication, I can use double line or triple-line; or I can use still other units of measurement. Instead of indicating distances to the bottom edge of the sheet, I can indicate the distances to (say) the bottom line position just as Well, as will be readily understood. I prefer to employ in dices involving no mental calculation nor memorizing, but I do not limitmyself in every case to the use ofany particular kind. number or order of indices Any mechanism having a mode of operation such as has been described,-that is to say, having an operative member that is first brought into a constant starting or initialposition, and then at a constant point in the sheets progress given a movement constant with that of vthe sheet,,can be made not only to operate indices, but to control and operate almost any formof signaling apparatus as well. In my drawings I show means for attracting the operators attention first through his eye, then through his ear, and after that, a means for rendering the machine inoperative, all

operated or controlled by the composite rotary member 6-11-67.

Having reference to my visual or eye signal I have shown herein the periphery of the part' 6 divided into two sections, the

one, the working section, consisting of the portion bearing the indicating marks or indices, and the other being left blank. The

working section is colored in striking con. trast to the other section-say a white background with black lettering thereon for the. one, and a solid black for the other. The

index-guide or pointer-piece 34 is shown ex:

tended out over the periphery as shown, so

that during the time the periphery is detained with the point 89 opposite the pointer, none of the white or lettered portion of the periphery will be visible to the operator, but when the periphery enters upon its working movements with the platen. the white or lettered portion will be brought into view and the black portion will disappear. The striking change from black to white will be noticed by the operator,

who will then understand that it is time, or near time, for him to remove his sheet. Such a signaling or indicating means could be used alone, without the addition of any lettered indices whatever, and without the addition of any other signaling means. The

- bell 2'7.

following means: I attach to the track 84.

which supports the carriage 12 in its transverse movements across the machine in the usual manner, andis in turn supported at either end in the usual manner by the frame 4;1, the angle-piece 85, and to this anglepiece I attach by means of the pin 86 the The bell may be supposed to hang about centrally between the frames 41. Also attached to track-beam 84 is the pin or axle 70, having journaled thereon the upwardly-extending trip-lever 69 and the downwardly-extending hammer-lever 72.

The lever 69 carries a stop-pin 71 to engage with'the 'lug 88 on-the said hammer-lever. Attached to the end of the-hammer-lever is the bell-hammer or clapper 26, adapted to fall by gravity against the said bell? 27. I now attach to the carriage frame 12 bymea'ns of the axle or pin 83 the serrated rockingpiece 81, a front view of which is shown in Fig. 7. This piece 81 must be imagined as rocking upon a similar supporting pin 83 attached to the similar carriage-frameend 12 at the-farther end of the platen, as will be understood; and it carries upon it the pin 82 projecting from the nearer end thereof, and the [)I'OjBCtlOllS 87 as shown.

The carriage frame 12 bears also the extension 22, upon which is journaled the rocking end 2 of the slotted shaft 73, shown more clearly in Fig. 6. The sleeve portion 7 of this shaftbears fixedly attached thereto the crank lever 78, which is connected with the before mentioned rocking piece 81 by means of the pins 79 and 82 and the connecting rod- 80,

and said sleeve portion also bears the up-' wardly-extending lever 1, which projects into the orbital path of the pin 68 stationed on the adjustable annular disk 67. he further or'inner end of the said telescoping shaft is journal'ed in the frame extension? 6, the said extension being attached to the further end-frame of the machine, the same resembling in form the end-frame 41 shown, as will be understood. The key-pin 30, Fig.

6, is merely used to hold the head 2 in po-'- sition upon the sleeve 7. \Vhen .it is time for the signal to be given, the pin 68. projecting from the disk 67 as fdescribed, e n' gages with the lever 1, which is thereupon pressed forwardly, and with it the rockshaft 2- 7-43 and the lever 78 thereon. This action rocks (lOW-l'HVtlIdly the serrated rocking piece 81, sothat the projections 87 thereon come into operative relation with the upper portion of the trip-leverGS). When now the carriage is returned inthe and keyed telescoping.

usual manner across the machine for the beginning of a new line, the projections 87 will alternately lift the bell-clap'perQG from the bell and release it, thus giving the operator an adequate signal.

The means whereby I render the machine inoperative are described thus: I prefer to employ means that will lock the printing mechanism of the machine in all cases at a predetermined point in the progress of the sheet, whether the printing at the time consists of a single column of numerals having short lines, or matter in longer lines, and whether it be positioned midway between the side edges of the sheet or far to .one side or the other of such position,-that is tov say, locking means. thatwill operate irrespective of the position of the carriage. The telescoping shaft 3, bears the projecting key 29, adapted to play in the slot 19 in 'the sleeve 7 The shaft 3 bears fixedly attached thereto the crank-lever 25, upon which is stationed the pin I journal be tween the main end-frames 41 of the Inachine the lock-gates 50, having an axle or arbor 48. Fixedly attached upon this arbor. or upon the lock-gate itself, the weighted lever 47, bearing the pin 46. The connecting rod 36 connects this portion of my mechanism...with' that previously described, 9

through the pins 46 and 33. When it is time for the machine to be rendered inop' erative, the pin 68, acting upon the lever 1, acts rockingly upon the sleeve? and through it the shaft 3 and crank-lever 25, thereby bringing the locking gate 50 into an upright position under the levers connected with the keys 59 and 39. These levers are the usual levers found in typewriting machines, and they may be imagined as lying behind the space-key lever 38, and in the same position relatively to the locking edge of the gate 50. The machine is now locked against further printing, whatever the position of the carriage and irrespective of its movement.

' In the illustrated construction the arrangement and setting of the parts are such that the first action of pin 68 upon lever 1 operates to draw the rocking-piece 81 down far enough to enable its teeth 87 to engage with trip-lever 69 of bell-clapper 26 in the return movement- Of the carriage, but does not turn the lock-gate 5O far enough to lock the type-levers. Thenext' turning movement' of the platen and pin 68 causes the rocking piece 81 to be drawn down somewhat farther and moves the lock-gate into Y its locking position.

I will now describe more particularly the use of my mechanism. Suppose -I Wish to leave a margin at the bottom of. my sheet equal to four double line-spaces: I bring my composite rotary member around, by twirl-- ing the p atensay, until the projecting piece 18 is conveniently stationed; then, lifting I weight 66 to move downwardly, thereby the said piece out of the recess in the edge of disk 16 occupied by it, I hold it and the disk 67 stationary while I turn the part (3 with its indices around until the numeral 8 lies opposite the said locking bar 18. I now release the bar 18, which falls into another recess, locking the disk- 67 again with the part 6 through the disk 16. My mechanism will now always give a preliminary eyesignal when the bottom of the sheet is approaching within its range; and when the paper-sheet is finally advanced into the last line position, it will ring a bell during the return of the carriage for the beginning of the line, thus advising the operator that.

the current line is the last line to be printed upon that sheet. If the operator disregards this signal and feeds forward the sheetafter printing such line, then returning the carriage to the beginning of the line, the bell -will be rung again during such return, and

the machine having been renderedv inoperative he can do no more printing. The parts may be set so as to cause the bell to be rung only upon the completion of the last line. If for any reason the operator wishes to print additional lines upon the sheet, he has butto turn the platen forward a line to release the lever 1 from engagement with the pin 68, and then backward into position, and his machine will be once more rendered operative. i I do not limit myself to the employment in all cases of the exact means shown for rendering the printing mechanism of a typewriting machine inoperative, nor to the use of any particular or special connecting means between the lockin mechanism and the actuatin means there or.

I show dlagrammatically two modifications of my more specific invention as described herein, in Figs. 3 and 5, the first illustrating a more direct connecting means betweenthe clutch-lever32 and the slot showing a friction-clutch of well-known strap type similarly connected.

In order for a mechanism. of this character to be completely operative, provision must be made for every. possible backingup movement of the sheet, and for the handling of wrinkled sheets and sheets having broken surfaces. I have made such provision by providing the paper-feeler with a hinge-joint 23, lug 65 and stop 24. as described, and by providing means whereby the parts 15 and 1 permit of a backing-up movement of the pins engaging upon them, from any point. If the mechanism be backed-up from the position of parts shown in Fig. 1 the paper-feeler instantly recedes from contact with the sheet, the backward movement of projection 14 permitting rocking sleeve 21 and moving the paperfeeler away from the paper-path. Should a chance roughness or irregularity in the backward-moving paper-surface meet the paper-feeler before the effective retraction thereof, the paper-feeler tip will merely the lower portion of the paper-feeler to bend idly backward upon pin 23. Slot 4' is made suflicienfily long to provide for anypossible movement of the paper-feeler on its axis, but ordinarily the combined retracting action and flexing action give clearance to the parts before the feeler has been carried backward into the slot very far. If. themechanism be backed-up from a still later position, after projection 14 has clearedstop 15, the said projection on encountering the stop merely lifts the same idly out of its path, as before explained. This novel backing-up action while desirable is not necessarily an essential part of my invention, nor do I regard myself as limited to the exact special means described for its accomplishment in all cases. y y

The uses of the weight-leyer 74 and the weight 66 adjustablethereon are these: first,

through the action of the pin 62 upon the lug 63, to return the stop or lever 15 into an operative position; second, through the hub 21 to swing the paper feeler out of its slot and away from the paper table 8 toward the platen, in order that the enterin'g'sheet may not be obstructed; and third, to adjustably subtract for sheet-easing purposes from the forces pressing the paper-feeler against the sheet; that is to say, to enable the pressure of the paper-feeler upon the paper sheet to be rendered as light as may be desired, whatever the force applied against the lever 15 by the pin 14. For instance, suppose thatthe spring be of such a stiffness that I the pressure of the pin 14 upon the lever 13 in the clutch-releasing act-ion equals as much as half a pound, whether because of leverage circumstances or what. Such a pressure transmitted to the paperfeeler might be sufiicient to tear or mar any ordinary sheet. But by adding the weight (56, and adjusting it upon the lever 74 until it'bears backwardly against the pin 14. with a force equal to half a pound less half an ounce, the net pressure against the sheet. will be reduced to a half-ounce. Briefly stated, the principle involved is thatthe paper-feeler pressed against the sheet by the difference between two forces, the lesser of which,

namely that due to the action of the weight 66, subtracts for sheet-easing purposes from the pressure of the greater,

is not necessarily limited to any particular form, position, or mode of application in I the performance of its novel function, nor

do I regard my invention as necessarily de-' pendent upon the use of such differential pressure-regulating means. The weight need not be adjustable, but may be a fixed weight.
